Bib

ABSTRACT

A plurality of disposable bibs formed consecutively on sheet material and having a perforated tear line forming each bib, and also forming a pair of ties which are formed between the perforations of the bib and the perforated tear line to be placed around the neck of a wearer and tied behind. Each of the perforated tear lines extends outwardly from a centrally located nadir toward the outer edges at an angle less than 40* between the outer edges and the end of the perforated tear line. The distance between adjacent nadirs is 1.5-3 times the depth of the perforated tear line, and the width of the bib is 1-3 times the depth of the same perforated tear line.

QACHEL. D. DA\H5 ATTORNEYS BIB This invention relates generally todisposable bibs. More particularly, this invention relates to disposablebibs formed from a roll of sheet material which may be individually tornfrom said sheet material.

The principal object of the present invention is to provide a pluralityof disposable bibs formed on a roll of disposable sheet material.

Another object of the present invention is to provide a plurality ofdisposable bibs formed on a roll of disposable sheet material whereinthe bibs are easily torn from the roll.

Another object of the present invention is to provide a plurality ofdisposable bibs of a simple design which is effective to be held inplace by a pair of mutually opposed ties that are adapted to be receivedand secured around the wearers neck.

A further and more particular object of the present invention is toprovide a unique perforated tear line on the disposable sheet materialwherein the tear line provides, a) a pair of ties, b) forms the upper orneck portion of the bib and, at the same time, c) forms the bottom ofthe next succeeding bib.

A further and more general object of the present invention is to providea plurality of disposable bibs which are easily and simply used andwhich are far more economical than other forms of packaging bibs.

These and other objects of the present invention will become apparentupon careful perusal of the following specification and claim, includingthe the accompanying drawing wherein:

FIG. 1 is a plan view of the disposable sheet stock illustrating theposition of the perforated tear line forming the successive bibs.

FIG. 2 is a perspective view of a bib being torn along the perforatedtear line from the roll of disposable sheet material.

FIG. 3 is a view in elevation of the bib as it would be secured aroundthe neck of the wearer FIG. 4 illustrates the bib positioned upon andaround the neck of an infant wearer.

Referring to FIGS. 1 and 2, it may be seen that there is a roll ofdisposable sheet material generally provided with an inner core 12 tofacilitate the rolling of the sheet material. The sheet material isprovided with a unique perforated tear line 14 in successive andidentical curved shapes along the sheet material to form a plurality ofsections 16 which, when torn along the perforated tear line 14, formsthe bib I8 as shown in FIGS. 2, 3 and 4 particularly.

The disposable sheet material that may be used includes but is notlimited to the polyvinyl synthetic resins of a thermoplastic nature suchas polyvinyl chloride, polyvinyl acetate, polyvinyl acetal, polyvinylalcohol, polyvinylidene chloride, polyethylene, polypropylene, as wellas the various polyesters well known to form sheet materials.Additionally, there may be any one of the various cellulose derivativessuch as cellulose acetate, butyrate, cellulose nitrate, ethyl cellulose,methyl cellulose, the polycarbonates, and even nylon. Also, the commonlyused paper products that are formed into sheet material may be utilizedto provide the disposable bibs of the present invention. In fact, thematerial that is usable is not in any way limited for use as thedisposable sheet material.

The perforated tear line 14 is a unique score line that may be impressedinto the sheet material by any suitable mechanical means well known inthe art. The shape and form of the scoreline is unique in and of itself,particularly with its relationship to successive perforated tear orscore lines 14. The tear line 14 is positioned between the outer edges20 of the sheet material and is essentially a convex curved semioval. Asshown, the perforated tear line 14 is convex downwardly towards theplayout of the roll. However, the perforated tear line may be simplyreversed in mirror image that, viewing FIG. 1, the roll would be at theleft hand end of the figure rather than at the right-hand end as ispresently illustrated in FIG. 2.

The semioval perforated tear line 14 has its nadir centrally locatedbetween the outer edges 20 and the tear line extends upwardly in asmooth curve from the nadir 22 to meet the outer edges 20 at an anglealpha not greater than 40. With such a small angle, there IS formed atie means 24 composed of should pair of land 28 which are mutuallyopposed on each side of the sheet material, and which form the ties thatmay be secured as by a knot 30, as shown in FIG. 3, around the neck ofthe wearer such as the infant of FIG. 4.

The shape of the perforated tear line 14 must be in the general shape ofa substantial semioval. The depth as measured from the nadir verticallyto a line joining the ends of the perforated line 14 is shown as thedistance X and is important to define the other proportions of the bib.For instance, the distance between the adjacent nadirs should be 1 52 to3 times the distance X, and the width of the sheet material betweenedges 20 should be between 1 to 3 times the depth of the perforated tearline 14, or as shown, the distance X.

As may be clearly seen, the incorporation of the peculiar and novelshape of the perforated tear line 14 forms ties 28 and 30 between theouter edges which are of a length X, that is, the depth of theperforated tear line. The depth X of the perforated tear line may varyin commercial use between 5 and 15 inches although such sizes are notcritical.

In use, the roll of disposable bib sheet material is placed in asuitable dispenser in hospitals or institutions or in the home, and atany time a bib is desired, it may be torn from the remaining bibs on thesheet material, as shown in FIG. 2. Once removed, the ties 26 and 28 arepositioned around the neck of the wearer, as shown in FIGS. 3 and 4, andtied in a knot 30 or otherwise secured together in any convenientfashion to hold the bib 18 secure on the chest of the wearer. It may beseen that with the simple roll of disposable bibs, the conveniencefacilitates the frequent use and disposing of the bibs after use by theattendant or mother without necessity of washing or cleaning the bib,and always providing a fresh clean sanitary surface to be secured forprotection of the wearer.

From the foregoing detailed description, it will be evident that thereare a number of changes, adaptations and modifications of the presentinvention which come within the province of those skilled in the art.However, it is intended that all such variations not departing from thespirit of the invention be considered as within the scope thereof aslimited solely by the appended claims.
